Definitions

  • the present invention relates generally to a slide adjuster for use in adjusting the position of an automobile seat in a direction longitudinally of a vehicle body and, in particular but not exclusively, to a reinforcing structure for a slide adjuster having a seat belt anchor mounted therein.
  • Some automobile slide adjusters include a seat belt anchor, and such slide adjusters have a predetermined strength so that when a large load is applied to an upper rail from a seat belt through the seat belt anchor, the upper rail may not be separated from a lower rail.
  • a stopper attached to a front portion of the upper rail is held in contact with a leg of the lower rail, while a striker secured to a vehicle floor is inserted in a recess defined in a rear end portion of the upper rail.
  • the slide adjuster as disclosed in Document 1 cannot be applied to a seat such as a driver's seat or a seat next to the driver, the position of which can be appropriately altered depending on a seat occupant.
  • the present invention has been developed to overcome the above-described disadvantages.
  • the automobile slide adjuster includes a lower rail to be secured to a vehicle body, an upper rail slidably mounted on the lower rail, a seat belt, a seat belt holding plate secured to the upper rail and having a seat belt anchor formed therewith to hold one end of the seat belt, and a reinforcing plate mounted to the lower rail to reinforce the seat belt holding plate.
  • This construction can effectively increase the strength of separation between the seat belt anchor and the rail with a relatively small space without increasing the thickness of the lower rail or the upper rail.
  • the automobile slide adjuster also includes an auxiliary rail joined to the seat belt holding plate and an auxiliary rail guide held by the reinforcing plate and having a guide groove defined therein, wherein a portion of the auxiliary rail is loosely inserted in the guide groove in the auxiliary rail guide.
  • the automobile slide adjuster further includes a belt mounted to the reinforcing plate and a belt guide secured to the seat belt holding plate to guide the belt.
  • the automobile slide adjuster further includes a guide support secured to the reinforcing plate to support the auxiliary rail guide and a guide support holding member secured to the seat belt holding plate to hold the guide support.
  • the guide support holding member is positioned laterally outwardly of the belt guide.
  • FIG. 1 is an exploded perspective view of an automobile seat with a slide adjuster according to the present invention
  • FIG. 2 is a perspective view of the slide adjuster according to the present invention.
  • FIG. 3 is a top plan view of the slide adjuster of FIG. 2 ;
  • FIG. 4 is a front view of the slide adjuster of FIG. 2 ;
  • FIG. 5 is a side view of the slide adjuster of FIG. 2 ;
  • FIG. 6A is a sectional view taken along line VI-VI in FIG. 3 , depicting the case where a load less than a predetermined value has been applied to a seat belt anchor through a seat belt;
  • FIG. 6B is a view similar to FIG. 6A , but depicting the condition in which a load greater than the predetermined value has been applied to the seat belt anchor to thereby deform an auxiliary rail;
  • FIG. 6C is a view similar to FIG. 6A , but depicting the condition in which the auxiliary rail has been separated from its guide.
  • FIG. 1 an automobile seat A provided with a slide adjuster according to the present invention.
  • the slide adjuster includes a pair of slide adjuster units S disposed on respective sides of the seat A for use in adjusting the position of the seat A in the longitudinal direction of a vehicle body.
  • each slide adjuster unit S includes a lower rail 2 extending in the longitudinal direction of the vehicle body and rigidly secured to a vehicle floor, and also includes an upper rail 4 mounted on the lower rail 2 so as to be slidable relative thereto.
  • a generally rectangular seat mounting frame 6 is joined to the right and left upper rails 4 , and the seat A is mounted on the seat mounting frame 6 .
  • the lower rail 2 has a cross section generally in the form of a figure “U” and is held by a U-shaped channel 8 .
  • the right and left U-shaped channels 8 are connected to each other by front and rear connecting members 10 .
  • the upper rail 4 has a cross section generally in the form of an inverted figure of “U”, and the seat mounting frame 6 has front and rear overhangs 6 a extending laterally outwardly towards a central portion of the vehicle body.
  • a seat belt holding plate 12 has a horizontally extending inner side portion 12 a , which is joined to an upper surface of one of the right and left upper rails 4 that is positioned on the central side (tunnel side) of the vehicle body.
  • the seat belt holding plate 12 also has a first inclined portion 12 b extending laterally outwardly and obliquely upwardly from the inner side portion 12 a , a horizontally extending medial portion 12 c extending laterally outwardly from the first inclined portion 12 b , a second inclined portion 12 d extending laterally outwardly and obliquely upwardly from the medial portion 12 c , and a vertical portion 12 e extending upwardly from the second inclined portion 12 d .
  • the vertical portion 12 e has a seat belt anchor 14 formed therewith.
  • a planar auxiliary rail 16 is joined to a lower surface of the horizontally extending medial portion 12 c of the set belt holding plate 12 so as to extend laterally outwardly.
  • a reinforcing plate 18 has a horizontally extending inner side portion 18 a , which is joined to a lower surface of one of the U-shaped channels 8 that holds the lower rail 2 positioned on the central side of the vehicle body.
  • the reinforcing plate 18 also has an inclined portion 18 b extending laterally outwardly and obliquely upwardly from the inner side portion 18 a , and a horizontally extending portion 18 c extending laterally outwardly from the inclined portion 18 b .
  • An auxiliary rail guide 20 made of, for example, a resin is mounted on an outer side portion of the reinforcing plate 18 , and a guide support 22 is secured to the outer side portion of the reinforcing plate 18 to support the auxiliary rail guide 20 .
  • the auxiliary rail guide 20 has a guide groove defined therein, in which an outer edge portion of the auxiliary rail 16 is loosely inserted.
  • the seat belt holding plate 12 and the reinforcing plate 18 have such a positional relationship that the first inclined portion 12 b of the former and the inclined portion 18 b of the latter extend parallel to each other, and the horizontally extending medial portion 12 c of the former and the horizontally extending portion 18 c of the latter extend parallel to each other.
  • a belt 24 Opposite ends of a belt 24 are secured to the inclined portion 18 b of the reinforcing plate 18 confronting the seat belt holding plate 12 , and a belt guide 26 having a guide groove defined therein, in which the belt 24 is loosely inserted, is secured to the first inclined portion 12 b of the seat belt holding plate 12 by a bolt 28 and to the horizontally extending medial portion 12 c of the seat belt holding plate 12 by a bolt 30 .
  • a guide support holding member 32 is secured to a portion of the vertical portion 12 e of the seat belt holding plate 12 that is positioned laterally outwardly and obliquely upwardly of the belt guide 26 . The guide support holding member 32 acts to prevent opening of the guide support 22 to thereby hold the guide support 22 in position.
  • front and rear ends of the lower rail 2 that is positioned on the side of a door are secured to the vehicle floor, and front and rear ends of the horizontally extending portion 18 c of the reinforcing plate 18 are likewise secured to the vehicle floor, while the automobile seat A is secured to front and rear ends of the seat mounting frame 6 on the side of the door and to the front and rear overhangs 6 a.
  • the upper rail 4 When the vehicle is running, the upper rail 4 is held on the lower rail 2 at the predetermined position by means of a known locking device. During a stop of the vehicle, if adjustments of the position of the seat are desired, the lock of the upper rail 4 with respect to the lower rail 2 is released by releasing the locking device, and subsequent application of a load to the seat in the longitudinal direction of the vehicle causes the upper rail 4 to slide along the lower rail 2 .
  • the locking device is operated at a desired position, the upper rail 4 is again locked with respect to the lower rail 2 , and the seat is held at such a desired position.
  • the auxiliary rail 16 slides along the auxiliary rail guide 20 with the outer edge portion of the auxiliary rail 16 received in the guide groove in the auxiliary rail guide 20 .
  • a portion (latch release) of a seat belt (not shown) that is retractable into, for example, a pillar of the vehicle body is latched in the seat belt anchor 14 , thereby protecting the seat occupant in the event of a collision of the vehicle or the like.
  • the strength of the seat belt holding plate 12 withstands the load F and, at the same time, the strength of the reinforcing plate 18 similarly withstands the load F because the auxiliary rail 16 joined to the seat belt holding plate 12 is received in the auxiliary rail guide 20 .
  • the slide adjuster according to the present invention can effectively increase the strength of separation between the seat belt anchor and the rail with a relatively small space without increasing the thickness of the lower rail or the upper rail, it can be effectively utilized in an automotive vehicle having a reduced space between the floor and the seat such as, for example, a one-box car, a truck and the like.
